ジャーナル フリーChactas braziliensis Lourenço, Aguiar & Franklin 2005 was described on the basis of four adult females collected in the state of Amazonas, Brazil, and represents the only species of this genus in the country. In this paper, the male of this species, which has never been recorded, is described for the first time by using a specimen taken from the state of Acre, Brazil. Males of C. braziliensis can be distinguished from those of oth- er small (up to 35 mm) Chactas species (C. adornelae Rossi 2014 and C. koepckei Lourenço & Dastych 2001) by the numbers of pedipalp femur carinae and pectinal teeth.抄録全体を表示PDF形式でダウンロード (2581K) -

ジャーナル フリーThe family Atypidae is reported from Rovno amber for the first time on the basis of a juvenile specimen described here as Atypus sp. It is fourteenth family of spiders reported from Rovno amber. Balticatypus Wunderlich 2011, a genus known from three species from Baltic amber, and the tribe Balticatypini Wunderlich 2011 are synonymised with Atypus Latreille 1804 and Atypini Thorell 1870 respectively. The diagnoses of the fossil genus and tribe were primarily based on the relative size of spinnerets of the first nymph, which are subjects of the ontogenetic changes. Our study reveals that the nymphs of the extant European species of Atypus have the same size and shape of the spinnerets as in the species described from the Baltic amber.抄録全体を表示PDF形式でダウンロード (4912K) -

ジャーナル フリーA phrurolithid spider species, Phrurolithus splendidus Song & Zheng 1992, is newly recorded from Japan. This species resembles P. pennatus, but can be distinguished from the latter by male tibial apophysis with thin finger-shaped apex, and spermathecae located behind openings.抄録全体を表示PDF形式でダウンロード (663K) -

ジャーナル フリーChrysilla lauta Thorell 1887 is the type species of the genus Chrysilla. Zhang & Wang (2017) formally recorded the female of C. lauta for the first time, but it does not include the description of important characters in spider taxonomy such as the palp of males and the epigyne of females. We here redescribe C. lauta in detail, on the basis of the comparison with the holotype, and DNA barcoding using mitochondrial CO1 fragment.抄録全体を表示PDF形式でダウンロード (3042K) -

ジャーナル フリーAlthough laboratory trials suggest that stick insects (Phasmatodea) are a highly palatable prey group for spiders, field observations confirming this hypothesis are very rare. We report on a predatory event involving a huntsman spider of the genus Damastes (Araneae: Sparassidae) on a stick insect of the genus Antongilia (Bacillidae: Antongiliinae) from Madagascar. Despite the anti-predator adaptations that characterise this insect group (e.g. the cryptic camouflage) the stick insect was recognized and overwhelmed by the sparassid spider.抄録全体を表示PDF形式でダウンロード (4831K) -

ジャーナル フリーHyllus diardi (Walckenaer 1837) is recorded for the first time from India on the basis of female specimens collected from Assam. Description of the specimen is given with figures of its body and genitalia. This species is distinguished from its congeners by the distinctive large hairy body, unique abdominal patterns and structure of epigyne.抄録全体を表示PDF形式でダウンロード (2397K) -

ジャーナル フリーTwo new species of the spider family Tetragnathidae (Araneae) from Japan are described: Glenognatha osawai sp. nov. and Pachygnatha monticola sp. nov. Glenognatha osawai is described on the basis of specimens collected on the Ogasawara Islands (Nakodo-jima and Muko-jima Islands). This new species is similar to G. argyrostilba (O. Pickard-Cambridge 1876) and G. tangi (Zhu, Song & Zhang 2003) in general appearance and cheliceral morphology, but it can be distinguished by the shapes of conductor, cymbium, and paracymbium of the male palp. Pachygnatha monticola is described from Nagano Prefecture, a mountainous region of Honshu Island. This new species resembles P. quadrimaculata (Bösenberg & Strand 1906), but it can be distinguished by the morphology of chelicera and fang and by the shapes of embolus and paracymbium of the male palp.抄録全体を表示PDF形式でダウンロード (3144K) -

ジャーナル フリーRe-examination of the syntypes of Damarchus excavatus Gravely 1921 raised doubts on its generic allocation. A new genus Gravelyia gen. nov. is proposed to accommodate the species. A new combination Gravelyia excavatus (Gravely 1921) comb. nov. is proposed, and a lectotype is designated for the species. Furthermore, a new species Gravelyia striatus sp. nov. is described from West Bengal.抄録全体を表示PDF形式でダウンロード (12242K) -
